This is a known feature of audio over low-bandwidth links, such as modems.
The delta-mod compression works for some folks, but not for others. I'd be
very interested in seeing a TraceRoute listing for you, since you seem to
have such a bad time of it all. When I experienced the same thing I
noticed that one router between the outer world and me had a horrid
latency. Getting rid of it did the trick. Your provider may suck, in
other words. Or their provider.
